'.IO ALIi WIIOM IT MAY CONOERN:

Be it known that I, WILLIAM Snnvrss, ofSidney, i n the county of Shelby,and State of Ohio, have invented certain new` and useful Improvements inApparatus for Soldering Tin Cans; and I do hereby declare that thefollowing is a full, clear, and exact description ofthe same, refe-r'neebeing had to the accompanying drawings, making a portion of thisspecification, in which- Figure 1 is a side View of an apparatusconstructedaccording to my invention;

Figure 2 is a vertical transverse section of the same.

Figure 3 is a side view of the same on a reduced scale, showing themanner of removing the can after the soldering-operation is performed. I

Figurci; is adetached section of a portion of the same on an enlargedscale.

Similar letters of reference indicate corresponding parts in all thefigures'.

This invention is designed more particularly for use in making tinfruit-canspbut it may also rbe employed to advantage in the manufactureof other cylindrical vessels of suoli material, and its object is toenable the operation of soldering the-joints of such tinwareV to beperformed with much greater convenience and economy of timethan ispracticable by the ordinary method of soldering.

The invention consists in a tubular holder, furnished, near one end,with an annular clasping-lip, in such manner that the can `may bereadily secured upon the said holder, and held in such position that itsjoints may be soldered with very great facility.

The invention further consists in the combination, with the aforesaidholder, of a knob or equivalent device, whereby the easy removal of theni`shed or soldered can or article from the holder is secured.

To enable others to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.I

A represents a cylindrical shell, which may be made of stiff sheetmetal, and which is made somewhat-for instance, about an inch-longerthan the cauur vessel to be soldered; and secured around one end of thisshell is an annular sheet-metal stra-p, B, placed preferably upon anintermediate band, a', whieh'keeps it at a short distance from the shellA, the innermost edge, a, of'which is made iiaring outward, the saidedge constituting a lip,tlaring from the surface of the shell A, asshown more clearly in g. 2. Secured in that end of the shell A at which,the strap B is situated isv a strong transverse bar, Z1, to the outerside of which is attached a knob, C, the purpose of which will be hereinpresently set forth. g n

In using the apparatus, the sheet-metal blank from which the cylindricalbody of the can or vessel is to be formed, having been first bent intoproper cylindrical shape, is placed around the shell A, with what isdesigned for the upper edge of the can'pushed underneath the lip, a, ofthe said shell, and with its longitudinal edges lapping past each otherto any desired degree. The bottom4 of the can is then tted upon theouter or lower end of the body of the can, the position ofthe said bodyand bottom of the can upon the apparatus .being shown more clearly inthe red' outline of g. 2. By this means the upper edge of the body isheld snugly in position by the lip a surrounding the same, while thelower edge is correspondingly retained in place by the lanch of thebottom placed thereon, as just mentioned. The partsrof the can beingthus secured in position, the joints are soldered by the usualor anysuitable means or appliances, which being donc, the knob C is placedbetweenY the prongs of a forked or bifureated tool, b, fixed to asuitable support, as shown in red outline in iig. 3, and the can, beinggrasped by the hands, as represented in the said ligure, is thenwithdrawn from the'apparatus. .lne apparatus, by -thus serving to holdthe body and bottom of the can in position while the joints thereof arebeing soldered, docs away with the necessity of the means ordinarilyemployed as prerequisites of such solderingoperation.

The shell may be made slightly tapering toward that end thereof oppositethe lip a, if desired, to facilitate the detachment of the soldered orfinished can or article therefrom.

I I a`m aware that cylinders provided with a lip of about half an inenwide to bite on the lap of the seam to be soldered have heretofore beenused; but these have proved of little value where perfect uniformity ofsize is desired, as the cylinder to bc soldered is aptto bulge away fromthe former onV the opposite side from said lip or clip; and; in case thematerial is less tha-n the average thickness. it will notI beheld by itat all. lh l, therefore, I do not claim; butl What I claim as myinvention, and desire to secure by Letters Patent, is

1. "The holder, composed of the shell A, furnished with the annular lip(1,' substantially as and for tho purpose herein set forth.

2. The comonaton, with the holder,

purpose specified. Y
